One of the challenges of searching for “technosignatures” (i.e. signs that intelligent life somewhere in the universe has created technology) is understanding what to look for.

Technology is a very broad area, and different types would show up as different features.

One of the most commonly cited is a Dyson sphere, which attempts to encapsulate a star and capture it’s outgoing light to produce energy.

But while we’ve looked for the mid-infrared waste heat these structures would produce for decades, we haven’t found a definitive instance of one.

According to a new paper, available in pre-print on arXiv by Turkish high school student Sahin Torlakcik, that might be because we are looking for the wrong type of energy all together.
